Transcript of Marine Biome

Marine BiomeThere is not really a climatograph for the Marine biome because it is hard to know the precipitation and temperature for the middle of the ocean and it varies so much. So i chose an island that is in the Marine biome like Hawaii for a climatograph. Map with locations of Marine biomesMarine Biome Food WebMajor Environmental problemsPhysical CharacteristicsAbiotic FactorsInhabitants Natural Resources How animals have adapted to the climate?Referenceshttp://marinebio.org/oceans/ocean-resources.aspMarine Biome has many natural resources. It provides around 200 billion pounds of fish and shellfish a year. It is mined for salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt can be found in the deep sea. They also drill for crude oil. The ocean is also used for humans and transportation Oceans regulate earths climate, they remove carbon from the atmosphere and then provides it with oxygen. There is also a whole bunch of organims in the ocean that have potential to fight diseases.There is many things going wrong in the oceans at the moment, here are only a few problems:

Acid in the oceansScientists have seen a huge increase in acid in the oceans, the acid has increased 10 times faster than it should. the amount of acid in the oceans right now is what it should be in a century from now. This has scientists thinking that the oceans are changing faster than we thought. Humans have made a 30 percent rise in ocean acidity by our carbon dioxide emissions. when carbon dioxide from our atmosphere dissolves in the oceans it makes carbon acid, which is very bad for marine life. With the acid increase the skeletons and shells of many marine species like hard coral, seaweed and sea urchins begin to corrode. This affecting the marine food chain.Overfishing Overfishing is when you take wildlife from the oceans at rates which the organisms in the biome cannot replace. This is very bad for the food chain. Since there has been such a collapse in large fish populations people are going deeper into the ocean, therefore father into the food chain. This is called fishing down and it is disrupting the ancient food chain a lot. It is said that by 2048 all the worlds fisheries will collapse if overfishing like this keeps up. Scientists say that it is possible to get the population of fish back up if we have aggressive fishery management Sea Temperature Risewhen climate change warms the earth is warms the oceans with it, but the oceans are a lot more sensitive to even the slightest temperature change. This affects the marine food chain a lot, krill reproduce in a lot smaller numbers with the temperature rise, this effects the animals that eat krill like penguins, which then effect bigger predators. The rise also effects coral, the reefs will release there symbiotic algae. Bleaching slows corral growth, making a greater chance of disease which leads to a large scale reef die off. It also makes sea levels rise by the heat makes the water expand. The consequences of this can be shoreline erosional and stronger storms http://ocean.nationalgeographic.com/ocean/protect/http://www.oceanicresearch.org/education/films/adap.htmlThe Marine Biome can be a very hard place for wildlife to live. Organism have to be constantly watching for predators and searching for food. There are many ways animals in the sea have adapted to make these tasks easier for them. Some have camouflage to hide from predators or to sneak up on their prey, or some others have coloration to make them stand out. Some animals simply hide from predators while others stay in groups out in the open feeling safe in the numbers. Animals skin have adapted by some have dangerous spikes on them or they are very venomous. All animals have adapted someway to catch there food, some feed at the bottom of the food chain while others feed at the top making all creatures in the oceans both predator and prey.There are millions of different kinds of species in the oceans but humans have only discovered less than 5% of the oceans. Here is a list of a few of the creatures that have been discovered:http://www.motherearthnews.com/nature-and-environment/fun-surprising-facts-about-the-oceans.aspx#axzz2kjUuI4IlWhalesBaleen WhalesBlue WhalesBlue Whales Fact SheetHumpback WhalesHumpback WhalesHumpback Whale Fact SheetKiller WhalesOrca, The Killer WhalewalrusSea turtle BarracudajellyfishPufferfishCoral ReefsSea HorseShark(many different kinds)Fish( many different kinds)Sea CucumberLobsters Dolphins ManateesStarfishSquid Sea UrchinsWaterWaterSandRocksWavesOxygenLight(from sun)http://openocean2012p2.edublogs.org/abiotic-and-biotic/The Marine Biome has 3 areas, oceans, coral reefs and estuaries http://www.ehow.com/info_8425169_characteristics-marine-biome.htmlOceansThe Ocean is separated into 4 zones. The intertidal which is where the ocean meets the shore, it contains lots of algea and small animals. The next zone is pelagic, it is the open ocean. It contains lots of seaweed and marine mammals plankton and fish. Another zone is the benthic zone, it is the bottom of the ocean with sand and dead organisms lay. The last zone is the deepest and coldest part of the ocean ocean and it is called the abyssal zone. There are very few nutrients there so only few invertabrates and fish live there.Coral ReefsThere are three types of Coral Reefs. Barrier, Fringing and Atoll.They are located mostly in warm shallow waters.EstuariesEstuaries are where the freshwater rivers meet the saltwater ocean. is the home to many plants and animals. It also contains seaweeds, marsh grasses and in the tropics, mangroves.
